Leaving the UV disinfection light on is inexpensive and necessary for ensuring that all bacteria is removed and you are never exposed to harmful contaminants.
Your UV lamp will last for approximately one year (or 9,000 hours). For simple maintenance, every system is installed with an alarm to notify you when it is due for a change.
The frequency of filter changes will depend on the quality of the water entering the system. As with all water-using products, we recommend changing filters at least every 12 months, ensuring the water supply for your whole house stays free of sediments, chemicals, and bacteria. Please consult your water technician to determine your cartridge replacement schedule.

Understanding Rainwater Quality and Filtration Needs

Rainwater tank filters are critical elements that ensure the quality and usability of collected water. As simple as it might seem, choosing the right filter for your rainwater tank involves more than just picking the first option you come across.

It requires careful consideration of various factors that influence the water quality collected and the longevity of your rainwater harvesting system.

In this guide, we’ll delve into the nuances of selecting the ideal rainwater tank filter. From understanding the typical contaminants in rainwater to evaluating the different types of filters available, we aim to arm you with the knowledge needed to make an informed decision.

Whether you’re setting up a new rainwater harvesting system or looking to upgrade your existing one, this blog will walk you through the essential factors to consider.

The Basics of Rainwater Quality

Rainwater, as it falls, is often considered pure. However, as it travels down your roof and into your rainwater tank, it can collect a variety of contaminants from your gutters and the surface of your roof. These include organic matter such as leaves and bird droppings, atmospheric pollutants, and particles from roofing materials.

Understanding these potential contaminants is crucial as they significantly influence the type of filtration system required for your rainwater tank.

Determining Your Filtration Needs

The specific filtration needs for your rainwater tank depend largely on the environmental conditions and the type of roof you have. For example, a roof in an industrial area might gather more chemical pollutants, while a roof under heavy tree cover might collect more organic debris.

Assessing your local environmental conditions is a key step in determining the right filter for your system. It’s important to consider not only the immediate surroundings of your property but also the broader environmental factors.

Maintenance and Durability Factors

Ease of Maintenance

Regular maintenance is key to the optimal performance of your rainwater tank filter. This includes tasks like cleaning and replacing core components, such as the UV light and filter cartridges. The ease of maintenance can vary significantly between different types of filters.

When selecting a filter, consider how accessible it is for maintenance. Filters that are easy to clean and maintain can save you time and effort in the long run, especially if you can replace them yourself rather than paying a technician to come out and service the system for you.

Durability and Lifespan

The materials and build quality of a filter directly impact its durability and lifespan. Filters made from high-quality, robust materials may cost more upfront but can withstand the rigours of constant use and environmental exposure, resulting in fewer replacements over time. It’s also essential to consider the manufacturer’s warranty and the expected lifespan of the filter.

Some filters might need replacing every few months, while others can last for years. Balancing initial costs with long-term durability will help you make a cost-effective decision.

Cost and Budgeting for Your Rainwater Tank Filtration System

Initial Cost vs. Long-Term Value

Filters vary significantly in price based on type, quality, and capacity. While some may seem economical upfront, they could require frequent replacements or be less efficient, leading to increased long-term costs.

Conversely, more expensive filters often offer greater efficiency and longer lifespans, which can be more cost-effective over time.

Budgeting for Replacement Filters and Maintenance

Apart from the initial purchase, budgeting for ongoing expenses such as replacement filters and maintenance is vital. The frequency and cost of replacements depend on the type of filter, water quality, and usage.

Regular maintenance, such as cleaning and inspecting the filters, may also incur costs, especially if professional services are required. Planning for these expenses ensures that your system remains operational without any unexpected financial burdens.
